Do not chil, seo seo sea cdr,, September 1, 2025 / Prnewswire / – What started as a daring idea in 2011 is now an important step in Asia Clean energy story. The monsoon wind energy project has officially reached its cod August 22, 2025becoming the first cross -border renewable energy project in Asia. Today, 600 MW of clean power and on the scale of public services extends from the mountains of Southern Lao RDR in VietnamStrengthen regional energy security, stimulate economic growth and trigger aspirations of the ASEAN network by showing what is possible when nations work together.
Extending through the Dak Cheung district in Sekong province and the Sanxay district of the province of Attapeu, 133 wind turbines rise from the Rigelines, regularly turning in the strong and reliable winds of the region. This is the product of more than a decade of detailed wind studies. Their energy travels four stations of 115 kV, increased to 500 kV at the under-ending of the project and transported along a high voltage line of 27 kilometers on the Lao-Vietnam border, where it connects to Vietnam 500 kV transmission system. From there, the transmission line continues 44 kilometers additional so that Thanh My Sonnedat d’Evn.
The project was launched by Impact Electrons Siam (IES) and is developed and operated by Monsoon Wind Power Company Limited, an incorporating Lao company. It is supported by an international shareholder consortium: Impact Electrons Siam, the initiator of the project, Acen de The PhilippinesBCPG Public Company Limited and STP & I Public Company Limited ThailandMitsubishi Corporation of Japan And its subsidiary in exclusive property, Diamond Generating Asia, Limited (DGA) and SMP consultation Sole Company Limited from the PDR Lao.
Funding comes from a group of main regional and global lenders whose support reflects deep confidence in its technical, environmental and economic merits. These include the Asian Development Bank (BAD, as a lead arrangement), Asian Investment Bank (AIIB), Japan International Cooperation Agency (JICA), Export-Import Bank of Thailand (Exim Thailand), Hong Kong Mortgage Corporation (HKMC), Sumitomo Mitsui Banking Corporation (SMBC), Kasikornbank (Kbank) and Siam Commercial Bank (SCB). The construction was led by Powarchina, with wind turbines provided by Envision Energy.
“It’s a proud and historic moment for our company, our partners and the region,” said Nat Hutanuwatr, managing director of the Monoon Wind Power. “From the beginnings when many doubted the feasibility of a cross -border wind farm in this field, to overcome technical, logistical and financial challenges, this success testifies to the determination, innovation and collaboration of all those involved, including our shareholders, lenders, advisers, entrepreneurs, technology providers, Héroic myons.
“Good things take time,” said Paradai Suebma, president of Monsoon wind energy. “The wind of the monsoon, 14 years old in progress, is a tribute to the vision, the partnership and our commitment to sustainability. We recognize the foresight of the IES, which has created this project, and expand our deepest appreciation to our management and our team of the Mousson wind power project, whose devotion and perseverance indefective for the reality of clean energy. Regional, while shaping a model for connectivity to clean energy.
We really appreciate the opportunity to contribute to regional growth while shaping a model of clean energy connectivity. We also in depth the collaboration of our partners, lenders, advisers and entrepreneurs to make this step possible. And above all, the confidence and the edifying quality of life of the communities that we serve make our heart grow and gives this achievement its greatest meaning. “”
By diversifying Laos’ Energy mixture beyond hydroelectricity and food Vietnam With clean electricity, the wind of the monsoon directly supports the Asean Power Grid initiative, reduces dependence on fossil fuels and advances the energy transition of the region. The project should compensate about 1.3 million tonnes of CO₂ per year.
About the Mosson wind energy project
The monsoon wind energy project began in 2011 as an ambitious vision to exploit the strong and coherent winds of the Southern PDR Lao and offer clean energy through borders. Extending around 68,000 hectares of mountainous land in the Dak Cheung district in Sekong province and the Sanxay district of the province of Attapeu, it is now Southeast Asia The largest terrestrial wind farm, with an installed capacity of 600 MW.
The 133 turbines of the project are supported by four 115 kV substations for energy collection and a 500 kV substation to intensify the voltage before transmission. From there, electricity moves along a high voltage line of 27 kilometers at the Lao-Vietnam border, then continues an additional 44 kilometers through the transmission system of 500 kV of EVN to reach the Thanh My Substation. He operated under an electricity purchase agreement of 25 years with EVN and a 28 -year concession agreement with the RDR Lao government.
Representing an investment of approximately $ 950 millionMonsoon Wind is funded by a consortium of main international and regional lenders, reflecting deep confidence in its technical, environmental and economic merits. More than a decade of wind measurement data guided the optimal placement of each turbine, ensuring maximum performance and efficiency.
Beyond clean energy, the project has brought significant local advantages. Since the start of construction March 2023The Monoon Wind Project has created at least 1,600 jobs, more than 1,000 of which were filled with Lao nationals. These roles have built precious skills and livelihoods in the region.
An annual $ 1.1 million The Community Development Fund supports improvements in education, health care, agriculture and infrastructure in the surrounding villages. The first initiatives include scholarships for local students to study abroad, mobile health assessments leading to doctors and nurses to villages far from the project area and means of living for coffee – such as sowing distribution, training provision and techniques’ sharing to improve harvesting and household income.
The key infrastructure includes a 500 kV deputy on the project site, four 115 kV substations, 250 hectares of permanent land use and cross-border grid interconnection facilities.
On August 22, 2025The 600 MW Monsoon wind project has managed to deliver electricity to EVN, marking a historic first for renewable cross -border energies in Asia. During his 25 -year operating life, he should avoid more than 32.5 million tonnes of CO emissions – equivalent to the elimination of around 7 million road cars for a year, or planting around 59 million trees and allowing them to grow for 25 years.
